Danfoss 014L0186 Sight Glass

The Danfoss 014L0186 (SGN 22s) is a professional-grade sight glass and moisture indicator designed specifically for integration into the liquid lines of commercial refrigeration and air conditioning systems. This model features 7/8" ODF solder connections, providing a high-integrity, leak-free joint suitable for high-pressure environments. Engineered for a broad spectrum of HFC and HCFC refrigerants—including R134a, R404A, R407C, and R507—it utilizes a sensitive N-type moisture indicator. This technical indicator provides a clear color transition from Green (Dry) to Yellow (Wet) to alert technicians of moisture levels that could lead to acid formation or system contamination. With a maximum working pressure of 500 psig (35 bar) and an operating temperature range of -58°F to 175°F, this sight glass is built to withstand rigorous field conditions. The internal glass is optimized for high visibility, allowing for immediate identification of refrigerant subcooling issues or flash gas presence, ensuring the system is operating at peak thermal efficiency.

• Enhanced System Monitoring: Provides real-time visual assessment of the refrigerant's physical state and moisture content to prevent compressor failure.
• Universal Compatibility: Validated for use with a wide range of refrigerants (HCFC, HFC, HC, and R744) and oil-free applications.
• Durable Construction: Features a corrosion-resistant brass body and high-strength copper connections for long-term reliability in varying climates.
• Technical Precision: Minimal color-change dependence on temperature ensures accurate moisture readings across the entire operating range.
• Safe Design: Complies with PED and UL standards, including suitability for ATEX Zone 2 explosive atmospheres when used with flammable refrigerants.

• What does it mean when the indicator turns yellow? A yellow indicator signifies that the system's moisture content has exceeded permissible limits (typically 30-75 ppm depending on refrigerant type), indicating that the filter drier is saturated and requires immediate replacement.
• Can this be used on the discharge line? No, sight glasses are specifically designed for the liquid line, typically between the filter drier and the expansion valve, to monitor subcooling and moisture.
• Is this compatible with newer low-GWP refrigerants? Yes, the SGN series is compatible with many R448A, R449A, and R513A blends; always verify specific PPM thresholds in the Danfoss technical data sheet.
